Abstract

The detection method is based on ascertaining the output voltage level of a radiation-responsive detector and comparing the output signal deviation frequency from a preset reference level with a predetermined reference signal frequency. The output of the radiation-responsive detector (1) is taken directly and also via a time-delay device (3) to a differential amplifier (5). The amplifier (5) output is connected directly and also via a reference follow-up circuit (9) to a comparator (10,11). The output of the comparator (10,11) is connected via an additional time-delay device (12,13) to the output regulator (17).
